Hi, I'm sorry for the lack of info.
Intel I7-8700K Water cooled
MSI Z370 Gamin Pro
8Gb DDR4 (Croshair i believe)
M.2 Samsung 970 Evo 500gb
2x Kingston 128gb SSD
2x Seagate 5Tb drive
Evga GTX 1080 TI SC Hybrid
Evga Supernova 850W
Windows 10 Pro (tried fresh install from usb, guess early build and after latest update)
Long story short.
I had a i7-7700K until this summer when my PSU blew up and fried mb, memory and CPU. Got myself parts above after. GPU seemed fine and has been working perfectly until now.
GPU is a little over 1 - 1.1/2 year. Rest is around 5 months.
M.2 is a week old. <- Could this be the reason? Everything is fast and W/R speed is on point.
Reinstalled windows Wednesday afternoon and it worked without any issues for around 4 hours yesterday.
i thought it could be one of the game broke it, but after a few hours with that game trying to replicate the error i swapped to another "easier on the hardware" game and went straight to black screen. So i guess its either HW or windows causing the issue.
I even had in without any games running.
